Goku scratched his head with a sheepish laugh. "Great… my body's back to normal again. What a pain!"
Gohan and the others gasped. "Dad's Super Saiyan 4 power… it's gone!"
One-Star Dragon looked like he'd just won the lottery. "So your battery ran out already, huh?"
"When you two were so focused on that fusion trick, you both took way too many of my hits."
"Running out of energy was bound to happen."
He sneered at Vegeta. "And you're next, Vegeta. It's only a matter of time."
"Don't blink," he snarled, raising his hand as a terrifying wave of energy pulsed in his palm. "I'll end you right now!"
Vegeta's face twisted in rage. "End me? Don't you dare underestimate Vegeta!"
Goku, back in human form, clenched his fist. "You're strong, I'll give you that. But don't think I'll go down that easy!"
And then—
A strange glow appeared on Goku's forehead. The very Dragon Ball he had swallowed earlier—the Four-Star Ball—suddenly surfaced.
Both Vegeta and One-Star Dragon froze in shock, staring at Goku's glowing forehead.
Mr. Satan rubbed his eyes. "H-Hey, am I seeing things, or does Goku have a Dragon Ball stuck on his head?!"
Vegeta's jaw dropped. "Kakarot! Don't tell me… you're about to turn into an Evil Dragon yourself?!"
Goku blinked, confused. "Huh? Why's everyone staring at me? Do I got something on my face?"
"Grandpa, your forehead!" Pan shouted.
Goku touched his forehead and jumped. "Whoa! What the heck is this?! How did the Four-Star Ball end up here?!"
He paused, then shrugged. "Well… guess it's fine."
Gohan and the others: "…"
One-Star Dragon slowly floated up, his aura flaring. "You've impressed me, actually fighting me this long, risking your lives."
"Son Goku, your spirit's admirable."
"But it ends now."
His whole body erupted with terrifying energy, unleashing a massive shockwave straight at Goku and Vegeta.
Just then, the Four-Star Ball on Goku's forehead blazed with light, shooting free into the air.
"Hold it, One-Star Dragon!"
A familiar figure burst forth, punching One-Star's attack aside like it was nothing.
The Four-Star Dragon had returned!
He dropped into a fighting stance. "Goku's mine to defeat. Nobody interfere."
One-Star's face darkened. "Four-Star Dragon… don't get in my way."
Goku frowned. "Wait, Four-Star Dragon, what's going on? Why are you siding with him again? Don't you remember he killed you?"
One-Star laughed mockingly. "It's useless. Any Dragon Ball absorbed into my body gets corrupted by my negative energy. That's why this guy's back—resurrected through evil."
"Even if you swallow the Four-Star Ball yourself, it won't matter."
Four-Star Dragon smirked. "That's right. I'll be the one to take you down, Goku."
Vegeta scoffed. "Another fool who doesn't know his place. Out of my way!"
He teleported and charged in—only to get kicked out of the sky by Four-Star Dragon.
BOOM!
Vegeta slammed into the ground, cratering it.
"Careful, Vegeta!" Goku shouted. "He's way faster than me!"
Vegeta stood, brushing off dust. "Shut it! I don't need you telling me that!"
Four-Star Dragon blurred forward, firing a blast.
Vegeta vanished just in time. "Don't underestimate me!"
The two began a high-speed clash, teleporting back and forth across the battlefield. But no matter how fast Vegeta went, he couldn't shake Four-Star Dragon.
A blast finally caught him—
KA-BOOM!
The explosion ripped apart the battlefield. Buildings disintegrated, the ground trembled, and everything was consumed in blinding white.
When the smoke cleared, Vegeta lay motionless, his fate uncertain.
"Vegeta! Vegeta!!" Goku roared.
One-Star Dragon smirked. "Nicely done, Four-Star. You've finally shed that naïve act. Now you truly look like one of us Evil Dragons."
"Go on—finish Goku for me."
Four-Star Dragon turned to Goku. "With pleasure."
In a flash, he kicked Goku aside like a ragdoll.
One-Star leaned back, amused. "Goku's just a regular human again. He can't possibly stand against a Dragon revived by my negative energy."
Four-Star charged another deadly blast, firing straight at Goku—who barely dodged by leaping away.
"Kame… hame…"
But before he could fire, Four-Star teleported and smashed him down with a punch.
Goku hit the ground hard.
One-Star frowned. "What's he doing? Goku's just a weakling now—he should've been crushed instantly."
Trunks rushed to Vegeta's side. "Dad! Are you okay?!"
Vegeta groaned, getting up. "That guy… I don't get it. His attack looked deadly, but it barely hurt. He wasn't even fighting seriously."
One-Star barked, "Quit stalling, Four-Star! Finish him already!"
Four-Star pointed his hand at Goku, energy gathering again.
…
In the real Dragon Ball world.
On Namek, Krillin looked baffled. "What does Vegeta mean? That Evil Dragon's holding back? But his moves look deadly!"
Future Goku shook his head. "I don't know what's coming. But I believe in the Dragon Ball my grandpa left me. It can't be all bad."
Frieza's laugh echoed. "Saiyans… so naïve. You're about to die and still dreaming. Vegeta just got lucky. That so-called Evil Dragon will kill you all."
In the Naruto world
"Come on, Goku! Get up! You're supposed to be a Super Saiyan—take that guy down already!" Naruto yelled, fists clenched.
Sasuke rolled his eyes. "Idiot. Can't you see? Goku's powerless now. They've already lost."
In the One Piece world.
At Marineford, Akainu's fists smoked with fury. "We can't let evil win. Justice must prevail! Goku, get up and fight for what's right!"
Kizaru yawned lazily. "Scary stuff… otherworldly guys sure are terrifying."
…
Back on the battlefield.
Four-Star Dragon aimed his attack at Goku. "I'll end this now."
One-Star stood. "Do it! Send Son Goku to hell!"
But Four-Star's face stayed calm. "I know. Except… the one going to hell this time—"
"—is you."
Goku suddenly rose to his feet, eyes blazing. "That's right! You!"
"Kame… hame… ha!!"
Both Goku and Four-Star unleashed their blasts—
But they weren't aimed at each other.
They both fired straight at One-Star Dragon!
KA-BOOM!
The explosion engulfed him in smoke and fire.
Before he could recover, Four-Star teleported behind him and locked him in place.
"..."
